Prefrontal association of subthalamic deep brain stimulation with rapid eye movement sleep behavior disorder in Parkinson’s disease

Subthalamic nucleus (STN)-deep brain stimulation (DBS) in Parkinson's disease (PD) patients affects not just focused target areas but also diffuse brain networks. The effect of this network modulation on nonmotor DBS effects is not fully understood. By concentrating on the sleep domain, the authors comprehensively determined the influence of electrode location and related structural/functional connections on changes in probable rapid eye movement (REM) sleep behavior disorder (pRBD) symptoms after STN-DBS, which has been reported to ameliorate, deteriorate, or remain constant.
